As near as I can tell (undoubtedly most of you know spim better than I do), SPIM buffers up input until you hit return, then extracts and returns to pl/0 the first number it finds in the buffered line, discarding the rest of the line. So, I think you need to enter the input 1 2 0 3 4 on 5 consecutive lines, one number per line: 1 2 0 3 4

Several people have asked me about groups. There's a lag in creating group directories, so they probably won't be ready in time to use for this week's HW. (you can still work as a group; you'll just need individual copies of the files.) If you do decide to work as a group on this one: 1) Please tell me who's in your group, 2) Turn in only ONE (hardcopy) of the class hierarchy and only ONE (electronic) copy of convolve per group, and 3) Please CLEARLY mark the hardcopy with the list of group members, so everyone will get credit. You get to pick who you want to work with; I don't assign group memberships (but let me know if you can't find a partner - maybe I can do some match making).

I'd suggest you discard old versions you might have and copy new ones before beginning HW#2. [Specifically, discard the obsolete files pas and io.c, and get updated copies of stmt.codegen.c, expr.codegen.c and Makefile; I think that's all I changed.]
Date: Sun, 11 Oct 1998 20:10:17 -0700 From: "Walter L. Ruzzo" <ruzz at s.washington.edu> To: cse40 at s.washington.edu Subject: 3.7a 3.7a seems to be confusing people. The problem says: "All strings of letters that contain the 5 vowels in order." first, the 5 English vowels are a e i o u. "In order" means alphabetical order, i.e. as listed above. I take this to mean that a string is in the language if you can underline exactly 5 letters in it, so that you've underlined one a, one e, one i, one o, and one u, and futhermore the underlined a is somewhere to the left of the underlined e, which in turn is somewhere to the left of the underlined i, etc. The underlined letters may or may not be adjacent to each other, may or may not start at the left end of the string; there may or may not be other vowels in the string; there may or may not be non-vowels in the string. E.g.: the rain in sp_ain d_escends ma_inly to the gr_o_und Does this help?

Algorithm 3.3 step 3c seems to be needlessly complex, and 3b seems > to be flawed. (As pointed out in class). 3b is not flawed, although I didn't make that clear. What I argued in class is that joining 2 *arbitrary* NFAs as in 3b does *not* correctly implement concatenation. However, Algorithm 3 doesn't join arbitrary NFAs; it only joins the special kinds of NFAs that are built (inductively) by algorithm 3, and it *is* sound in that case. Why the difference? Well, as you'll recall, the problem with applying 3b to arbitrary NFAs is that if the 2nd machine can return to its start state, and if the 1st machine can exit from its final state, then this might allow the joined machine to hop back and forth between the two sub-machines on the way to accepting a string. [Recall my example: the 2-state machine for odd number of 0s concateneted with the 2-state machine for odd number of 1s.] However, Algorithm 3 guarantees that the NFAs it builds have (i) no edges into the start state and (ii) no edges out of the final state. Step 3b is correct for machines of this restricted kind. (In fact , either (i) or (ii) alone would be sufficient.) The need to preserve restrictions (i) and (ii) is exactly why step 3c looks "needlessly complex" - it's more complex than the version I showed in lecture, but my version didn't preserve (i) and (ii), since my analog of 3b doesn't need them. Is my version better than the book's version? Not clear; mine sometimes generates more states and epsilon moves, sometimes fewer. Which should you use for the homework? I don't care, BUT SAY WHICH YOU ARE USING so Ashish knows what to expect.

Date: Wed, 14 Oct 1998 19:51:05 -0700 (PDT) From: Justin Miller <justi at s.washington.edu> To: cse40 at s.washington.edu Subject: Doing PL/0 on NT To do the PL/0 project on NT, you'll need to do a couple things. First off, you want it to agree with MSVC: 1) Download all the .c and .h files to some NT folder. 2) Make a new project workspace like usual, add all the .c files 3) Under Project->Settings (Alt+F7), select the "C/C++" tab. At the bottom of the panel is a window with a bunch of compiler flags. At the end of this mess, add the flag "/Tp". This will make the .c files compile as C++ files. 4) There are a few discrepancies that MSVC will warn you about, or just plain won't compile: a) The method isMarked() in class RegisterBank (reg.h) has an implicit cast to bool that MSVC doesn't like. Replace the line with: bool isMarked(Reg reg) { return (_bank & nthBit(reg)) != 0; } b) token.h has the line "#include <strings.h>". Replace this with #include <string.h>. strings.h in /usr/include is just a one-line file that says "#include <string.h>". c) MSVC *still* doesn't do scoping of loop variables according to the final draft of the C++ standard, so any time two 'for' loops appear with the declaration "int i = 0;" in them, it complains. Solve this this by making the second declaration "int j = 0"; this way it will still compile in Unix. d) In regs.h, SymTabScope is declared as a struct for use in the RegisterBank class, but later defined in symtab.h as a class. Change the reg.h declaration to a class. Okay, that should get your PL/0 compiler to compile. :) Next you need PC SPIM, which is available via anonymous ftp at: ftp://ftp.cs.wisc.edu/pub/spim/spimwin.exe Just type that into your web browser. You can also download the SPIM documentation from: ftp://ftp.cs.wisc.edu/pub/spim/spim_documentation.ps An online version is at: http://www.cs.bilkent.edu.tr/~baray/cs224/ref/spim.html Finally, a "SPIM Quick Reference", made from the Appendix A of your beloved 378 textbook, is available at: http://www.cs.bilkent.edu.tr/~baray/cs224/quickspim.html If you want to get SourceSafe set up, I think you'll have to talk to someone in support. I am lucky and have an office machine that allows me to make my own SourceSafe databases.... Enjoy! -Justin

I say this because not everybody in the class know each other or have any contact outside the class, and it may be very difficult to know who has a group and who doesn't, and who to approach and how to contact them ... You can also announce this in class on monday so those who need a group can get together after class outside the door. Alternatively, all who are in need of a group, plz respond to this email.

Please communicate among yourselves to set up groups. I can invent a grouping if you prefer, but it's probably better to do it yourselves. If any existing pair wants a third member, that's also OK. My estimate is that the base compiler is 5000 lines; you'll add/change 1-2000 lines. That's not unmanageable for one person alone, but as I've said, I think there's a definite benefit to having a partner to talk with, even if it doesn't save any time at all.

"Best way to evaluate" - you tell me what you think is best; there isn't a gold-standard answer to this. A few criteria that makes sense me, however, are that (1) you shouldn't *greatly* complicate the parser to do something that could be *simply* done during semantic analysis, and (2) you probably shouldn't complicate the parser to do a partial job at checking something that will have to be rechecked later anyway. On the other hand (3), it's generally better to catch errors early, so *do* include in the parser as much as you can conveniently include; it will simplify later processing. I realize that having seen only a skimpy outline of the "semantic analysis" material, these issues are perhaps a little murky, but I think they're still worth thinking about now. Here's a brain teaser along these lines: Which of the following are legal pl/0 expressions, and can you tell at parse time, or do you need to wait until later? var imareallyveryunusuallyextralongvariablename: int; 1 + 2 1 + true x + 2 x and true (x + 2) and x imareallyveryunusuallySuperlongvariablename + 5 Write a few sentence about the major design decisions that you faced, and why you made the decision you did.

So here is some explaination of what was required, what were some common errors and what could be a possible solution. o A comment in this context is a usual 'C' comment. So you allow things like /* xyz "abc */ de " pqrs */ and /* "a" xx "b" */ to be valid comments, but do not allow things like /* "a" */ "b" */ where the first occurance of */ is NOT inside quotes (it occurs BETWEEN the two quoted strings "a" and "b"). o A comment starts with a /* : beginComment = /* o You need to take care that a quoted string DOES NOT contain any quotes within it: QuotedStr = " {not(")} " Note: {R} here means 0 or more occurance of R. o Now, as long as you do not see a '*' or a '"', you can continue scanning the comment: NoSpecialChar = not(*,") o If you see a string of '*'s that is not going to end the comment, it must be followed by a QuotedStr or a character other than a '/' or a '"': StarString = {*} (QuotedStr | not(/,")) o Finally, you must see a string of '*'s that ends the comment: Endcomment = {*} */ -------------------- So our regular definition for comment looks like: BeginComment = /* QuotedStr = " {not(")} " NoSpecialChar = not(*,") StarString = {*} (QuotedStr | not(/,")) EndComment = {*} */ Comment = BeginComment { QuotedStr | NoSpecialChar | StarString } EndComment -------------------- -- Ashish

So we were wondering if we should > leave it as is, or if changing it for the sake of consistancy and "pretty > PL0 code" would be acceptable? :) some language designers have used "=" for const declarations like "const pi = 22/7" as a way of emphasizing the permanent identity between the name on the left and the value on the right, as opposed to the more ephemeral "pi := (gets) 22/7 right now, but I might change my mind any nanosecond". pl/0 follows this model. Clearly an arguable choice, but for the project PLEASE IMPLEMENT IT AS WRITTEN in the spec; we'll be running an automated set of test cases, and if you deviate from the spec in this (or any other) detail, our test suite and your compiler will not get along.

While going through various implementations of the (hand-coded) scanner, I found that all implementations (except one) did not have any checks for EOF while scanning comments. This could, in principle, lead to problems when there is no '\n' ending the last comment. If you figured out that THIS WILL NOT HAPPEN for our extension of the pl0_base compiler, and THEREFORE did not have a check for EOF, that's great. But if you missed the EOF check unintentionally, here's why your code still works correctly: The implementation of GetCh() uses a buffer that gets lines of input using the standard library routine "gets", and the result of "gets" is ALWAYS a string ending in '\n' (whether or not it read the last line of input) unless there are some `serious' problems with the input file. -- Ashish

I'd much, much rather talk to you during office hours, but would feel both forsaken and guilty if I sit in my office alone for the whole hour and neither talk to you nor go to the Extremely Boring Meeting, so Please Come To Office Hour, and Please Tell Me In Advance That You Will Come If I don't hear from you, I'll probably sigh and go to the Extremely Boring Meeting instead. 2) Wednesday 12/9: Another Extremely Boring Meeting, but this one I can't skip, so office hour will be shifted 1/2 hour later: 10:30-11:30. 3) After Wednesday: No regularly scheduled hours, but a. send mail or call (543-6298) & we can arrange something b. Is there interest in a review session before the final, say Monday afternoon or early evening? I could be persuaded...
